摘要： A multilayered LC composite component in which a fine adjustment to a desired frequency can be performed, includes multilayered body sheets on which internal electrodes including capacitor electrodes and inductor electrodes are stacked via dielectric layers. On surfaces of the multilayered body sheets, there are disposed a ground internal electrode and input/output extraction electrodes. A trimming electrode is arranged on the multilayered body such that the trimming electrode is opposed to some of the internal electrodes and is electrically connected to the ground internal electrode. In order to make a rough frequency adjustment, insular electrodes are isolated from the trimming electrode by trimming grooves. Then, a coating material is filled in each of the trimming grooves to make a fine adjustment.

摘要： An LC resonating component, such as multilayered LC filter 1, is provided having a high Q-value and a low profile. The filter 1 comprises an insulating sheet 2 having a ground electrode 3 on its surface and in its center a via hole 7 connected to the ground electrode 3, an insulating sheet 2 having a via hole 4 in its center, insulating sheets 2, 2 having capacitor electrodes 5, 6 on their respective surfaces, and a protective insulating sheet 2. The via hole 7 is connected to the via hole 4, wherein the via holes 4 and 7 together comprise an inductor conductive body 8. The inductor conductive body 8 is perpendicular to the planes defined by capacitor electrodes 5, 6, and thus the magnetic flux created around the inductor conductive body 8 does not penetrate the capacitor electrodes 5, 6.

摘要： A radio frequency IC device achieves impedance matching between a radio IC chip and a radiation plate in a wide frequency band, and achieves desired radiation characteristics over a wide range of frequencies. A radio frequency IC device and a radio communication system allow both long-distance and short-distance communication and, in particular, allow short-distance communication using a small amount of energy. The radio frequency IC device includes an electromagnetic coupling module including a radio IC chip and a feed circuit board, and a radiation plate. An annular electrode is arranged to be coupled to both a feed circuit of the electromagnetic coupling module and the radiation plate. The radiation plate defines an electric-field radiation plate for long-distance communication, while the annular electrode defines a magnetic-field radiation plate for short-distance communication. The feed circuit board may be removed, so that the radio IC chip is coupled to the annular electrode directly or with an interposer disposed therebetween.
